TECHNICAL FIELD
[0001] The present application relates to the technical field of automobile manufacturing auxiliary equipment, and particularly relates to a vehicle frame turnover machine. BACKGROUND
[0002] In the production and manufacturing process of automobiles, engineering machinery and the like, the vehicle frame as a core bearing component has complicated processing, assembling and repairing procedures. Due to the complex structure, large size and heavy weight of the vehicle frame, it is often necessary to turn over the vehicle frame in the above-mentioned procedures to realize processing and assembling at different angles or all-around repairing and testing, so that the vehicle frame turnover machine becomes an indispensable key equipment in such production scenarios.
[0003] There are various types of vehicle frame turnover equipment in the prior art, and common ones mainly include mechanical turnover racks and hydraulic drive turnover mechanisms. Among them, the mechanical turnover rack is mostly fixedly hinged and cooperated with a manual or simple power-driven structure, which has low turning angle adjustment precision, and needs the cooperation of multiple operators in the operation process, which not only has high labor intensity, but also has high safety hazards. Although the hydraulic drive turnover mechanism has certain improvement in driving force and stability, it generally has the problems of complex structure design and large space occupation, and the layout of the dragging transmission components of most hydraulic turnover equipment is unreasonable, which causes uneven stress on the vehicle frame in the turnover process, and easily causes local deformation of the vehicle frame, especially not suitable for the turnover operation of special-shaped or thin-walled vehicle frames.
[0004] In addition, the connection and cooperation between the cross beam frame body and the dragging assembly of the existing turnover equipment are poor, either unable to realize the coherent connection of the stable lifting and turnover action of the vehicle frame, or having high energy consumption and slow action response in the turnover process, which is difficult to meet the efficient and accurate operation requirements on modern production lines. At the same time, the versatility of part of the turnover equipment is weak, and complicated adjustment is needed for different specifications and models of vehicle frames, which further reduces the production efficiency and increases the use cost of the equipment. SUMMARY
[0005] Therefore, in order to solve the problems of complex structure and high cost of the existing auxiliary vehicle frame and the like turnover equipment, the embodiments of the present application provide a vehicle frame turnover machine.
[0006] The vehicle frame turnover machine provided by the embodiments of the present application comprises two vertical frames, a first cross beam, a first dragging assembly and a second dragging assembly, wherein, The two vertical frames are arranged symmetrically opposite each other. The first crossbeam is erected between the two vertical frames, and a second crossbeam is erected on the upper end of the first crossbeam. The first towing component is installed on the upper end of the second crossbeam. The lower end of the first towing component extends to the bottom of the first crossbeam and is connected to a third crossbeam. The upper end of the second towing component is connected to the lower end of the third crossbeam, and the lower end is connected to the vehicle frame to be flipped in the outside world, so that the vehicle frame can be flipped by the cooperation of the first towing component and the second towing component.
[0007] Furthermore, the first dragging assembly includes a first motor, a first dual-output speed controller, and two take-up drums. The first motor is fixedly mounted on the upper end of the second crossbeam, and its output end is drivenly connected to the input end of the first dual-output speed controller. The two output ends of the first dual-output speed controller are respectively drivenly connected to a first drive shaft. The two first drive shafts correspond one-to-one with the two take-up drums. One end of each first drive shaft is drivenly connected to the corresponding output end of the first dual-output speed controller, and the other end is drivenly connected to the corresponding take-up drum.
[0008] Furthermore, each of the winding drums is equipped with a first adapter shaft, each winding drum is fixedly sleeved on the corresponding first adapter shaft, and both ends of each first adapter shaft are respectively mounted on the upper end of the second crossbeam through first bearing seats. One end of each first adapter shaft passes through the first bearing seat on the corresponding end and is connected to a first coupling sleeve. The corresponding end of each first adapter shaft is connected to the corresponding end of the corresponding first drive shaft through the first coupling sleeve thereon.
[0009] Furthermore, each of the winding drums is wound with a lifting rope, one end of each lifting rope being fixedly wound and connected to the corresponding winding drum, and the other end being hinged to the corresponding end of the third crossbeam.
[0010] Furthermore, the second dragging assembly includes a second motor, a second dual-output speed controller, and two sprockets. The second motor is fixedly mounted at the lower end of the third crossbeam, and its output end is drivenly connected to the input end of the second dual-output speed controller. The two output ends of the second dual-output speed controller are respectively drivenly connected to second drive shafts. The two second drive shafts correspond one-to-one with the two sprockets. One end of each second drive shaft is drivenly connected to the corresponding output end of the second dual-output speed controller, and the other end is drivenly connected to the corresponding sprocket.
[0011] Furthermore, each sprocket is equipped with a second adapter shaft, each sprocket is fixedly sleeved on the corresponding second adapter shaft, and both ends of each second adapter shaft are respectively mounted on the lower end surface of the third crossbeam through second bearing seats. One end of each second adapter shaft passes through the second bearing seat on the corresponding end and is connected to a second coupling sleeve. The corresponding end of each second adapter shaft is connected to the corresponding end of the corresponding second transmission shaft through the second coupling sleeve thereon.
[0012] Furthermore, each of the sprockets is equipped with a chain, the upper end of each chain being engaged with the corresponding sprocket and the lower end being fitted onto the corresponding end of the frame.
[0013] Furthermore, the two ends of the lower end face of the first crossbeam are respectively fixedly connected to the upper ends of the two vertical frames.
[0014] Furthermore, a support frame is provided on the lower end face of the second crossbeam, the upper end of which is fixedly connected to the lower end face of the second crossbeam and the lower end is mounted on the upper end of the first crossbeam.
[0015] Furthermore, each end of the first crossbeam is provided with a labor-saving auxiliary component to assist the frame in flipping.
[0016] The beneficial effects of the technical solutions provided by the embodiments of the present invention are as follows: The chassis tilting machine of this invention, through the action of the first towing component, can adjust the height of the third crossbeam when needed, thereby expanding the working range of the second towing component. Simultaneously, through the action of the chain on the second towing component, the chassis can be tilted according to requirements for chassis processing and use. The two vertical frames are symmetrically arranged, providing a stable and symmetrical support foundation for the first and second crossbeams, ensuring balanced overall force on the equipment and avoiding structural tilting or deformation due to excessive force on one side, thus improving the structural stability during operation. The layered structure of the double-layered crossbeams (first and second crossbeams) achieves functional zoning: the second crossbeam provides an installation carrier for the first towing component, while the first crossbeam provides spatial guidance for the movement of the third crossbeam. At the same time, the double-layered structure can distribute the upper load, further enhancing the load-bearing capacity of the equipment and adapting to chassis tilting operations of different weight specifications. The installation position and connection method of the first towing component can drive the third crossbeam. The vertical lifting motion provides a stable lifting power source for the second towing component. Simultaneously, the first crossbeam limits the travel of the third crossbeam, preventing deviation during lifting and ensuring motion accuracy. The second towing component, acting as a connection between the frame and the third crossbeam, transmits the lifting power from the first towing component to the frame. In conjunction with the lifting action of the first towing component, the frame's tilting posture can be adjusted by adjusting the tension, meeting the needs of tilting at different angles. The collaborative working mode of the two towing components achieves graded power transmission and precise posture control: compared to a single towing component directly driving the frame tilting, the dual-component combination buffers the impact during tilting, preventing the frame from being bumped or deformed due to excessive instantaneous force. Furthermore, by separately adjusting the motion parameters (such as extension speed and travel) of the two towing components, it can adapt to frames of different sizes and shapes, improving the equipment's versatility and the smoothness of the tilting process.

Detailed Implementation
[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0020] Please refer to Figures 1 to 5 An embodiment of the present invention provides a vehicle frame tilting machine, which includes two vertical frames 1, a first crossbeam 2, a first towing assembly, and a second towing assembly.
[0021] In this embodiment, two vertical frames 1 are erected symmetrically on the working area, and a first horizontal beam 2 is placed between the two vertical frames 1. The lower ends of the two ends of the first horizontal beam 2 are fixedly connected to the upper ends of the two vertical frames 1, thereby forming a gantry-like structure that serves as the load-bearing structure for the entire device.
[0022] A second crossbeam 3 is provided on the upper surface of the first crossbeam 2. A support frame 22 is provided between the second crossbeam 3 and the first crossbeam 2. The upper end of the support frame 22 is fixedly connected to the lower end of the second crossbeam 3, and the lower end is fixedly connected to the upper end of the first crossbeam 2. In this way, the first crossbeam 2 and the second crossbeam 3 can be formed as a whole, so as to facilitate the installation of the first dragging component and the second dragging component.
[0023] By symmetrically erecting two vertical frames and fixing the lower ends of the first crossbeam to the upper ends of the two vertical frames, a gantry-like basic load-bearing structure is formed. This structure can stably support the weight of the first towing assembly, the second towing assembly, and the vehicle frame to be tilted, ensuring the structural stability of the device during operation. At the same time, a second crossbeam is added to the upper end of the first crossbeam and fixedly connected to it as a whole with the help of a support frame. This not only strengthens the deformation resistance of the crossbeam structure and prevents the crossbeam from bending and being damaged due to excessive towing load, but also provides a flat and stable installation base for the first and second towing assemblies, ensuring that the towing assemblies run smoothly during the vehicle frame tilting process, thereby improving the safety and reliability of the vehicle frame tilting operation.
[0024] Furthermore, the first dragging assembly includes a first motor 4 and a first dual-output speed controller 5, wherein the first motor 4 and the first dual-output speed controller 5 are both fixedly mounted on the upper end surface of the second crossbeam 3, and the output shaft of the first motor 4 is connected to the input end of the first dual-output speed controller 5, so that the power of the first motor 4 can be transmitted through the first dual-output speed controller 5; at the same time, in this embodiment, the axes of the two output ends of the first dual-output speed controller 5 are located on the same straight line, and their orientations are opposite.
[0025] The first towing assembly, by fixing the first motor and the first dual-output speed controller to the upper end face of the second crossbeam, relies on the overall stable structure of the second and first crossbeams to effectively disperse the vibration load generated during motor operation and power transmission, preventing components from loosening or being damaged due to vibration. At the same time, the power of the first motor is transmitted through the first dual-output speed controller, and the two output ends of the speed controller are collinear and opposite in direction, which can realize the synchronous and reverse distribution of power, ensuring that the subsequent actuators connected to the output ends can obtain a balanced and directional driving force, ensuring the synchronicity and stability of the frame tilting action, and improving the accuracy and efficiency of the tilting operation.
[0026] The first dragging assembly also includes two first drive shafts 6, wherein the two first drive shafts 6 correspond one-to-one with the two output ends of the first dual-output speed controller 5, and one end of each first drive shaft 6 is connected to the corresponding output end of the first dual-output speed controller 5, and the other end is directed away from the first dual-output speed controller 5.
[0027] Therefore, by setting two first drive shafts to be connected one-to-one with the two output ends of the first dual-output speed controller, and with the other end of the drive shaft extending away from the speed controller, the synchronous reverse power distributed by the first dual-output speed controller can be effectively transmitted and extended, adapting to the installation position requirements of subsequent actuators, avoiding connection interference between the power output end and the actuators due to spacing issues, while ensuring the stability and continuity of power transmission, providing continuous and balanced driving force for the frame tilting action, and further improving the power transmission efficiency and adaptability of the towing component.
[0028] The first dragging assembly also includes two take-up drums 9, each corresponding to one of the two first drive shafts 6. Each take-up drum 9 is equipped with a first adapter shaft 8, and each take-up drum 9 is fixedly sleeved on the corresponding first adapter shaft 8. Both ends of each first adapter shaft 8 are respectively mounted on the upper surface of the corresponding end of the second crossbeam 3 through first bearing seats 10. At the same time, the axis of each first adapter shaft 8 is on the same straight line as the axis of the corresponding first drive shaft 6. The end of each first adapter shaft 8 near the corresponding first drive shaft 6 passes through the first bearing seat 10 on the corresponding end and is connected to a first coupling sleeve 7. The corresponding end of each first adapter shaft 8 is connected to the corresponding end of the corresponding first drive shaft 6 through the corresponding first coupling sleeve 7. In this way, the first motor 4 can drive each first drive shaft 6 to rotate, thereby driving each take-up drum 9 to rotate.
[0029] Each winding drum 9 is equipped with a lifting rope 11, with one end of each lifting rope 11 wound around the corresponding winding drum 9 and the other end extending from top to bottom to the bottom of the first crossbeam 2.
[0030] A third crossbeam 12 is provided below the first crossbeam 2. The length direction of the third crossbeam 12 is consistent with the length direction of the first crossbeam 2. The lower ends of the two lifting ropes 11 on the two winding drums 9 are respectively hinged to the two ends of the third crossbeam 12. In this way, when the two winding drums 9 rotate, the third crossbeam 12 can be raised or lowered according to the actual working conditions.
[0031] Therefore, the first towing assembly, through the linkage design of the winding drum, lifting rope, and third crossbeam, transmits the power output from the first motor to the winding drum via the drive shaft and adapter shaft, driving the lifting rope to be wound and unwound synchronously, thereby achieving smooth lifting and lowering of the third crossbeam. At the same time, the coaxial transmission and synchronous counter-rotation structure of the two winding drums, combined with the hinged connection between the lifting rope and the two ends of the third crossbeam, ensures that the force on the third crossbeam is uniform and the posture is horizontal during the lifting process, avoiding tilting and jamming problems. Moreover, the bearing seat supports the bearings, reducing frictional loss in power transmission, ensuring the accuracy and stability of the lifting action, and providing a reliable lifting drive foundation for subsequent frame tilting operations.
[0032] The second dragging assembly includes a second motor and a second dual-output speed controller 13. Both the second motor and the second dual-output speed controller 13 are fixedly mounted on the lower end face of the third crossbeam 12. The output shaft of the second motor is connected to the input end of the second dual-output speed controller 13, so that the power of the second motor 4 can be transmitted through the second dual-output speed controller 13. At the same time, the axes of the two output ends of the second dual-output speed controller 13 are on the same straight line and their orientations are opposite.
[0033] The second dragging assembly also includes two second drive shafts 14, wherein the two second drive shafts 14 correspond one-to-one with the two output ends of the second dual-output speed controller 13, and one end of each second drive shaft 14 is connected to the corresponding output end of the second dual-output speed controller 13, while the other end is directed away from the second dual-output speed controller 13.
[0034] The second drag assembly also includes two sprockets 17, each corresponding to one of the two second drive shafts 14. Each sprocket 17 is equipped with a second adapter shaft 16, and each sprocket 17 is fixedly sleeved on the corresponding second adapter shaft 16. Both ends of each second adapter shaft 16 are respectively mounted on the lower end face of the corresponding end of the third crossbeam 12 through second bearing seats 18. At the same time, the axis of each second adapter shaft 16 is on the same straight line as the axis of the corresponding second drive shaft 14. The end of each second adapter shaft 16 near the corresponding second drive shaft 14 passes through the second bearing seat 18 on the corresponding end and is connected to a second coupling sleeve 15. The corresponding end of each second adapter shaft 16 is connected to the corresponding end of the corresponding second drive shaft 14 through the corresponding second coupling sleeve 15. In this way, the second motor can drive each second drive shaft 16 to rotate, thereby driving each sprocket 17 to rotate.
[0035] Each sprocket 17 is equipped with a chain 19. The upper end of each chain 19 is engaged with the corresponding sprocket 17, and the lower end is fitted onto the corresponding end of the frame 20 to be flipped. In this way, when the sprocket 17 rotates, it can drive the corresponding chain 19 to rotate, thereby causing the frame 20 to flip.
[0036] It should be noted that the first crossbeam 2 is provided with a force-saving auxiliary component 21 at both ends. The force-saving auxiliary component 21 used in this embodiment is an existing equipment technology that is widely used in the manufacturing industry. Therefore, it will not be described in detail here. Thus, in this embodiment, the two force-saving auxiliary components can assist in the flipping of the frame 20.
[0037] Therefore, the second towing assembly integrates the second motor and the second dual-output speed controller on the lower end face of the third crossbeam. Relying on the first towing assembly to drive the lifting and lowering action of the third crossbeam, it can adapt to the tilting requirements of frames of different heights. At the same time, the second dual-output speed controller outputs synchronous reverse power, which is transmitted through the second drive shaft and the second coupling sleeve to the coaxially set second adapter shaft and sprocket. With the meshing connection between the chain and the frame, it can drive the frame to achieve a smooth and synchronous tilting action. Moreover, the support design of the bearing seat reduces friction loss during power transmission, avoiding problems such as one-sided jamming and tilting when the frame is tilted, which greatly improves the adaptability and stability of the frame tilting operation.
[0038] The frame tilting machine in this embodiment operates as follows: the height of the third crossbeam 12 can be adjusted by the first dragging component, and then the height of the second dragging component can be adjusted according to the actual working conditions. Thus, the operating height can be adjusted according to the height required when the frame 20 is tilted. Furthermore, when the frame 20 is tilted, the tilting of the frame 20 can be assisted by the labor-saving auxiliary components on both sides.
[0039] In this document, the directional terms such as front, back, top, and bottom are defined based on the location of the components in the accompanying drawings and their relative positions to each other, solely for the purpose of clarity and convenience in expressing the technical solution. It should be understood that the use of these directional terms should not limit the scope of protection claimed in this application.
[0040] Where there is no conflict, the above embodiments and features described herein can be combined with each other.
[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
